Very Weak Recoil Action USP-C

I picked up a new USP-C yesterday and I am noting an issue with the recoil and slide. If I fire the gun it cycles and fires but the action is pretty weak compared to other GBBs I've had. When I cycle the slide manually even doing it fast I can feel a little hang up even though the wear markings look pretty good. The real issue is when I slow cycle the slide. It completely hangs about an inch from full close. I have noticed on my two other KWAs that they come close to hanging up but the spring pulls them through, albeit shakily. I don't expect airsoft guns to be as smooth as their real steel counterparts (Though you guys do a damn good job ).

So my question is. Is there a different spring one could recommend to add a bit more oomph but not hamper the backwards cycle? I know people put 150% 1911 springs on their 226 for example

By cycling fully I mean it is recoiling, slapping back the hammer, and properly chambering and firing the next ball. I haven't had any misfeeds or balls that squirt out the barrel (My NS1 KP45 has really never worked so I am familiar with how bad it could be). So from a "will it shoot and work" perspective it seems ok... I'll check out that spring set. Thanks.
